A statistically unlikely one. 40 packages out of 7500 is a very low hit rate..that's about 5 packages per machine over a week (duration of the build), so you'd probably have to run a single machine for a day or more under the right load pattern in order to trigger it. > vm/pipe sounds reasonable to believe for this kind of corruption, but > it never happened for me. > Possibly I'm not pushing vm that much. > I wonder if setting vm.idlezero_enable=0 has an influence - this will > not change the danger of this bug, but if it changes sympotoms might > give a good indication of the direction to search. I'll give that a try. I suppose I'll have to revert the machines to an older -current to get away from the latest (DDB?) bugs.
